ARCHITECTURE
----------------------------------------------------------------

  This SAGA implementation is designed to be a reference
  implementation of the SAGA standard.  As such, it strives to

    - follow the SAGA API specification as close as possible
    - defines the C++ language bindings to SAGA (the SAGA spec
      itself is language independend)
    - allows to bind to multiple mittleware backends

  In particular the last point is of importance to the overall
  architecture:  As SAGA is designed to abstract arbitrary grid
  middleware, and as this implementation is designed to run on
  top of arbitrary Grid middleware, we decided to implement an
  plugin based system (plugins are named adaptors though, as
  they implement the adaptor pattern from well known the OO
  patterns).

  This software hence targets two different communities:

    - end useres aka grid application programmers:

      Grid application programmers are priovided with a standard
      complient SAGA implementation, and can use it to simplify
      the development process for their applications.


    - grid middleware developers:

      For grid middleware developers, this software provides
      a framework to bind the SAGA C++ reference implementation
      to their middleware, by using the adaptor system and
      infrastructure to easily code new adaptors to their
      specific middleware.  That way, thay can rather easily
      provide a SAGA complient Grid API to their Grid
      environment.
